Definitions
- the invention relates generally to a process for the production of fruit juice concentrate and in particular to a process for increasing the fruit juice yield in the production of fruit juice concentrate from citrus fruits.
- Fruit juices are non-fermented, but cookable, alcohol-free products, especially made from pome fruit, grapes and citrus fruits, which have the characteristic aroma, the characteristic taste and the characteristic color of the juices in question.
- the juices are obtained mechanically from fresh or cold-preserved fruits, which are freed of coarse and / or indigestible parts, such as peels and seeds, and made more durable by physical methods. - 2 -
- a problem in the production of fruit juices is that after the fruit has been crushed for production reasons (for example when juicing), unregulated enzymatic and other reactions occur, since with the destruction of the cells enzymes and other ingredients are no longer separated from one another by cell membranes.
- One way to prevent these undesirable reactions is to make a fruit juice concentrate.
- the mixture of pulp and fruit juice created after juicing is separated into fruit juice and pulp (pulp) by means of a passing machine.
- the fruit juice is then processed by concentrating it into fruit juice concentrate.
- the pulp can be preserved by heat treatment and cooling or aseptic packaging.
- the above-mentioned reactions can be prevented by these suitable processing steps.
- Fruit juice is restored by a back-dilution process in which the amount of water extracted from the concentration is returned to the fruit juice concentrate.
- all or part of the pulp removed before concentration can be added again.
- the transport costs are significantly reduced by the production of fruit juice concentrate in the country of production and the subsequent redilution in the consumer country, since the volume and weight of the concentrate are significantly reduced compared to the actual fruit juice.
- fruit juice concentrate is obtained from citrus fruits by separating the fruits into several constituent groups in a juicing plant, namely in peels, fruit skin, seeds and oil emulsion on the one hand and in pulp and fruit juice on the other. This mixture of pulp and fruit juice is then fed to a passing machine, where it is broken down into pulp and primary juice. The primary juice is then further processed in a known manner to produce fruit juice concentrate. - 3 -
- pulp obtained during the passage is subjected to pulp extraction, in which on the one hand pulp extract and on the other hand pulp residues are formed with the addition of water.
- pulp residues are waste materials and cannot be used for beverage production. They are therefore mostly dried and processed into animal feed or fertilizers, for example.
- the pulp extract is then fed to an evaporator.
- the aim of this process step is to thicken the pulp extract, for which purpose condensate is eliminated from the pulp extract.
- the pulp extract concentrated in this way is not suitable for the production of fruit juice and is mostly used as a raw material for soft drinks.
- the resulting pulp extract and thus also the concentrated pulp extract contain some ingredients which lead to a taste impairment of the soft drinks produced using the concentrated pulp extract.
- Vaping the pulp extract incurs manufacturing costs. Further fruit juice is no longer obtained.
- Figure 1 is a schematic representation of the process steps in a conventional method for the production of
- Figure 2 is a schematic representation of the method according to the invention for the production of fruit juice concentrate.
- FIG. 1 in which the known method for producing fruit juice concentrate is shown.
- microbially infected (rotten) fruits are sorted out.
- the remaining citrus fruits to be processed into fruit juice concentrate are then cleaned and fed to a juicing plant 1.
- the juiced and separated into two main ingredient groups includes peels, fruit skin, seeds and oil emulsion.
- the second group comprises a mixture of pulp and fruit juice.
- This mixture of pulp and fruit juice is then fed to a passing machine 2, where it is separated into primary juice and pulp.
- the primary juice is fed to an evaporator 3, where it is thickened.
- fruit juice concentrate and condensate are created as waste products.
- the fruit juice concentrate can now be stored in freezer tanks or filled into barrels. These containers are delivered to the juice manufacturer, where the fruit juice concentrate is further processed to produce drinkable fruit juice.
- the pulp separated in the passing machine 2 is subjected to pulp extraction 4. Pulp extract and pulp residues are produced with the addition of water. The pulp residues cannot be used for beverage production. They can therefore be dried and then further processed into cattle feed, for example.
- the pulp extract generated during pulp extraction 4 is fed to an evaporator 5.
- the pulp extract is thickened, with condensate and more concentrated
- Pulp extract arise.
- the concentrated pulp extract serves as the base material for soft drinks.
- FIG. 2 shows the method according to the invention for processing citrus fruits.
- the fruits are first sorted, cleaned and then fed to a juicing plant 1.
- the citrus fruits are also separated into two main groups of components, the first group being peels, fruit skin, seeds and oil emulsion and the second group being a mixture of pulp - 6 -
- This mixture of pulp and fruit juice can optionally be fed to a tube heater (not shown), where the quality-damaging enzymes are destroyed at temperatures of 90 to 115 ° C. and a residence time of 20-60 seconds. In some cases, even lower temperatures of more than 50 ° C are sufficient to achieve denaturation and consequent deactivation of the quality-damaging enzymes. Heating should take place as soon as possible after the fruit has been chopped or juiced, in order to keep the time period within which the enzymes are active as short as possible.
- the mixture of pulp and fruit juice is then fed (either directly from the juicing system or via the tube heater) to a passing machine 2, where it is separated into primary juice and pulp.
- the primary juice is fed into a buffer tank 6 and then further processed, as will be explained later.
- the primary juice can be recooled (if it was heated before it was passed) and degassed. It is also possible to free the primary juice from germs by high-short-term heating (at 90 - 115 ° C and 20 - 60 seconds). In some cases, lower temperatures of more than 50 ° C are sufficient to achieve denaturation and consequent deactivation of the quality-damaging enzymes. In this alternative, too, the heating, as explained above, should take place as quickly as possible after passing through, in order to keep the time period within which the enzymes are active as short as possible.
- the pulp obtained by the passing machine 2 is a mixture of pulp solids and fruit juice components remaining therein.
- the pulp is passed on to a decanter 7, where it is continuously separated into pulp residues and secondary juice.
- a decanter 7 instead of the decanter 7, other known forms of continuously operating centrifuges can also be used.
- the pulp residues are discharged via the decanter screw discharge, then dried and further processed, for example, into animal feed or used as fertilizer.
- the secondary juice from the decanter 7 can alternatively or in combination go through three different process routes:
- the first process route A is preferably used for secondary juices with a low bitter content.
- the secondary juice is subjected to a pasteurization 8 directly after the decanter 7, which can be done, for example, in a plate heater.
- the pasteurized juice is then fed into the buffer tank 6.
- the secondary juice is fed to a plate heater after decanter 7 and subjected to pasteurization 9 there.
- the pasteurized secondary juice is then fed to a centrifuge 12 in order to separate fine sludge constituents of the secondary juice, which are then fed into the buffer tank 6 in a certain dosage.
- the secondary juice freed of turbidity components is fed to a debittering system 13 and debittered by means of an adsorption column.
- the debittered juice is metered into the primary juice already contained in the buffer tank 6 in a quantity-dependent manner.
- the secondary juice is fed to a plate heater after decanter 7 and subjected to pasteurization 10 there.
- the pasteurized secondary juice is then cooled down to the inlet temperature for the evaporation system 11 and worked up to semi-concentrate (22 to 28 Brix).
- semi-concentrate is now fed to the centrifuge 12 in order to separate fine sediment components of the secondary juice, which are fed into the buffer tank 6 in a quantity-dependent dosage.
- the secondary juice ie the semi-concentrate
- the semi-concentrate which has been freed of turbidity components, is likewise fed to the debittering system 13 and debittered by means of an adsorption column.
- the debittered juice will - 8th -
- the primary juice contained in the buffer tank 6 metered in depending on the quantity.
- the semi-concentrate does not have to be fed directly to the centrifuge 12 after evaporation in the evaporator 11. Both process steps (evaporation and centrifugation) can also be carried out at different locations.
- the semi-concentrate can first be stored in deep-freeze tanks or filled aseptically into barrels, in which the juice is delivered to the juice manufacturer, where the following process steps are carried out.
- the mixture of primary juice, further processed secondary juice and sediment components contained in the buffer tank 6 is then fed to an evaporator 3, where the juice is thickened.
- fruit juice concentrate and condensate are created as waste products.
- the fruit juice concentrate can now be stored in freezer tanks or filled into barrels and later processed into drinkable fruit juice.
- the buffer tank 6 is not absolutely necessary for the method itself.
- the primary juice and the secondary juices further processed in the various process routes A, B and C can also be fed directly to the evaporator 3.
- the buffer tank 6 is used here only for the intermediate storage of juices that are not immediately to be further processed.
